Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically a sterile protective sleeve for PICC catheter insertion and adjustment. Background Technology

[0002] After PICC (Peripherally Inserted Central Catheter) placement, the recommended location for the PICC tip is the lower third of the superior vena cava or the junction of the superior vena cava and right atrial node (CAJ). According to the 2021 American Guidelines for Intravenous Infusion, the optimal placement of the tip of central venous access devices (CVADs) is the lower third of the superior vena cava or the CAJ, as the accuracy of the PICC tip placement is crucial for the patient. Superficial placement increases the risk of dysfunction, fibrin sheath formation, and venous thrombosis; excessive placement may increase the probability of arrhythmias, and the tip entering the heart can cause chest tightness, palpitations, and even cardiac tamponade or perforation, endangering life. Therefore, personnel placing the PICC tip should first understand the optimal placement to ensure patient safety. Clinically, after placement, the tip needs to be confirmed via chest X-ray. During the time between placement and X-ray, the sterile drape needs to be removed. If the standard position is not reached, readjustment and sterilization are required, increasing workload and affecting placement efficiency. Utility Model Content

[0021] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a sterile protective sleeve for PICC catheter insertion and adjustment, comprising:

[0024] A tightening opening 1 is provided with an adhesive part 3 at one end and a sterile transparent sleeve 4 at the other end. A sleeve opening 5 is provided at the other end of the sterile transparent sleeve 4. A tightening rope 6 is provided inside the sleeve opening 5, and a buckle 7 is provided at the other end of the tightening rope 6.

[0025] With the sterile transparent sleeve 4, the skin around the insertion site and the exposed catheter connector are completely covered by the sterile transparent sleeve during use to ensure a sterile environment. This allows for direct adjustment of the catheter after chest X-ray, eliminating the need for further disinfection and avoiding the risk of infection due to incomplete disinfection. In addition, the sterile transparent sleeve 4 is made of transparent material, which facilitates observation.

[0026] Example 2:

[0027] like Figure 2 As shown, the sterile protective sleeve for PICC catheter insertion adjustment disclosed in Embodiment 2 of this utility model has a structure that is basically the same as that in Embodiment 1, except that:

[0028] The inner wall surface of the tightening opening 1 is fixedly connected with anti-slip protrusions 2, and one end of the tightening opening 1 is fixedly connected with an adhesive part 3.

[0029] The other end of the tightening opening 1 is fixedly connected to a sterile transparent sleeve 4, which is made of a sterile, soft and elastic material.

[0030] With the anti-slip protrusions 2 and adhesive parts 3, the tightening opening 1 tightly adheres the anti-slip protrusions 2 to the skin surface during use, and the adhesive parts 3 fix the protective sleeve to the patient's wrist, thereby achieving a more secure fixation and preventing it from falling off.

[0031] Example 3:

[0032] like Figures 3 to 4 As shown, the sterile protective sleeve for PICC catheter insertion adjustment disclosed in Embodiment 3 of this utility model has a structure that is basically the same as that in Embodiment 2, except that:

[0033] The other end of the sterile transparent sleeve 4 is fixedly connected to a sleeve opening 5, and a tightening rope 6 is wound around the inside of the sleeve opening 5.

[0034] The tightening rope 6 has a certain degree of elasticity, and the other end of the tightening rope 6 is engaged with a buckle 7.

[0035] The latch 7 is composed of a sleeve 701, a buckle 703 and a spring 706, and through holes 702 are provided on both sides of the sleeve 701.

[0036] The top end of the sleeve 701 is slidably connected to a buckle 703, and limit holes 704 are provided on both sides of the buckle 703. A pressing plate 705 is fixedly connected to the top end of the buckle 703.

[0038] With the tightening rope 6 and the locking buckle 7 in place, the sleeve 5 is tightened by the tightening rope 6 during use, thereby achieving the effect of sealing the skin around the insertion site and the exposed catheter connector in a sterile environment. The tightening rope 6 is tightened and fixed by the locking buckle 7, thus achieving the effect of convenient and quick operation.

[0039] The specific procedure is as follows: First, a sterile transparent sleeve 4 is placed over the patient's wrist. The sterile transparent sleeve 4 completely covers the skin around the insertion site and the exposed catheter connector, ensuring a sterile environment. This allows for direct catheter adjustment after chest X-ray without the need for further disinfection, avoiding the risk of infection due to incomplete disinfection. The transparent material of the sterile transparent sleeve 4 facilitates observation. Then, the adhesive part 3 is attached to the patient's skin surface, using the anti-slip protrusions 2 and the adhesive part 3... The design allows for secure fastening of the sleeve 5 by tightening the opening 1, ensuring the anti-slip protrusion 2 fits tightly against the skin surface, and securing the protective sleeve to the patient's wrist via the adhesive part 3. This provides a more secure fixation and prevents the sleeve from falling off. Finally, pressing the buckle 703 with the pressing plate 705 and pulling the tightening rope 6 tightens the opening 5. The tightening rope 6 and the locking buckle 7 ensure that the skin around the insertion site and the exposed catheter connector are kept in a sealed, sterile environment. The locking buckle 7 further tightens and secures the tightening rope 6, making the operation convenient and quick.
